Intertwining Operators for Siegel Parabolics over Finite Fields

Nir Elber, Hahn Lheem

We consider degenerate principal series representations $Ind_{P}^{G} χ$ over finite fields, where $G$ is a classical subgroup of $GL_{2 n}$ , and $P$ is the…

Exponents of Jacobians of Graphs and Regular Matroids

Hahn Lheem, Deyuan Li, Carl Joshua Quines +1

Let $G$ be a finite undirected multigraph with no self-loops. The Jacobian $Jac (G)$ is a finite abelian group associated with $G$ whose cardinality is equal to the n…

On Characteristics of Hyperfields Obtained as Quotients of Finite Fields

Antonio Frigo, Hahn Lheem, Dylan Liu

Hyperstructures are a natural extension of regular algebraic structures in which one of the operations, known as the hyperoperation, is multivalued; a hyperfield is such an extensi…
